In this study, a binder was formulated using 85% blast furnace slag and 15% fly ash. Three different additives—marble powder, strontium mineral waste, and titanium dioxide—were incorporated as partial replacements for blast furnace slag at ratios of 5%, 5%, and 1%, respectively, to create geopolymer mortars. The impact of these additives on the flexural and compressive strength of the mortars was evaluated. Furthermore, SEM/EDX analysis was performed to assess the microstructural effects of the additives. The findings revealed that titanium dioxide resulted in the highest compressive strength, recorded at 65.7 MPa. The SEM/EDX analysis suggested that the samples demonstrated a homogeneous internal structure, indicating a robust bond among the components of the matrix.</dc:description><dc:date>2025</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/19726</dc:identifier><dc:identifier>https://doi.org/10.26701/ems.1695691</dc:identifier><dc:language>en</dc:language><dc:relation>European Mechanical Science</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/19726</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
